摘　　要：以某沿海石化区吹填淤泥地基加固为背景,在原有地基处理的基础上,进行了间距为1. 2 m和0. 9 m两种正方形布置、水泥掺量分别为12%和18%共4种组合的粉喷桩试验研究,分析了单桩竖向抗压试验和单桩复合地基抗压试验结果,表明粉喷桩加固吹填淤泥地基的效果明显,可供类似工程参考。Based on the reinforcement of dredged fill silt foundation in a coastal petrochemical area. On the original foundation treatment,four kinds of combination of cement injection piles with square spacing of 1. 2 m and 0. 9 m and cement content of 12% and 18% respectively are studied. The results of single pile vertical compression test and single pile composite foundation compression test are analyzed. The results show that cement injection piles have obvious effect on the reinforcement of dredged fill silt foundation. For reference of similar projects.
